sens, i dont have dreams about demons, but i do have a lot about ghosts, and boats (sounds wierd) and people like on the 6th sense, i know its cause of the stuff thats happened in the last year. and, i know how you feel, i just want them to go away.
I dont know, any like medical ways of getting rid of them, like pills or anything, because i usually dont even tell people about this, it would just worry them. but, i find, that at nite, if i leave my radio, or a cd player on all night, it really really helps me a lot.
Just a suggestion, works for me. good luck.
